东濮凹陷中浅层的勘探开发程度已相当高，向深层拓展勘探领域成为必然。从烃源岩、储盖层及圈闭等方面分析东濮凹陷特殊的地质条件，研究其北部地区深层油气从沙三段到现今的成藏机理和运移聚集过程，总结文留地垒带和卫城—濮城构造深层油气成藏模式，提出下一步勘探思路。

The degree of exploration and development in middle-shallow formation of Dongpu Depression is quite high. It is necessary to
expand exploration to deep formation. This paper analyzes the special geological condition of deep oil and gas reservoir and trap,
and studies the reservoir-forming mechanism from Es3 to the present in north Dongpu Depression. At last, it summarizes the reservoir
-forming model of deep oil and gas for Wenliu horst strip and Weicheng_Pucheng structure. The next exploration targets are
predicted.
